Be it known that I, WILLIAM E. Gon'roN, of Moline, in the county of Rock Island and State of Illinois, have invented certain new and vuseful Improvements in Bolting-Reel Frames; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the construction of the frames of bolting-reels, such as are used in milling and for other purposes.

The principal object of the invention is to with the middle part of the exterior ribs and provide a construction in reel-frames whereby with the heads. Fig. 6 is a section of the same, a great degree of strength or rigidity is ob` taken upon line x x of Fig. 5. Fig. 7 is a sec,- tained,With a minimum of weight in the parts, tion of the same, taken upon line y y of Fig. 5.`

The invention consists in the matters here- A A are the reelheads,which, as far as the inafter described, and pointed out in the apmain features of the improvement herein set pended claims. I

In a. prior patent, No. 304,682, granted to me upon the 2d day of September, 1884, I have described and claimed a bolting'reel the frame of which comprises spirally-directed longitudi nal ribs and other transverse connecting-ribs, said ribs being connected at their intersections and forming a unitary truss calculated to give rigidity to the reel. In the patent mentioned the truss construction above set forth is claimed broadly, but is illustrated as applied only in such manner that the truss-ribs are themselves adapted to support the cloth.

My present invention embraces a. construc tion in which two sets of spiral or obliquelydirected truss-ribs extending the full length of the reel and arranged to cross each other, and secured together at their points of intersection to form a truss, are employed in addition to the usual exterior longitudinal clothsupporting ribs to give rigidity to the reel structure, as will hereinafter fully appear.

The invention may be more readily understood by reference to the accompanying drawings, in whichm n Figure 1 is a side elevation of a hexagonal reel,showing one form of myimprovement, in which the reel-.heads are connected by a single set of longitudinal ribs supporting the cloth and two sets of oppositely-inclined spiral or obliquely-direoted' trnssribs, which are .con- I are forth are concerned, may be made'either of solid disk form or with radial arms. As shown in Figs. 8 and 4, said heads are understood to be of disk or solid form, with provision for feeding or discharging through hollow gud'- geons. As illustrated inthe other iignres, however, the heads are constructed with radial arms and adapted for the attachment of the ends of the truss ribs of the reel, ashereinafter fully set forth.

B B are longitudinal ribs of the reel arranged parallel with the axis thereof and attached to the heads A in any desired or preferred manner. In the hexagonal form of reel, Figs. 1 and 5, said ribs sustain the cloth at the corners of the reel in the usual manner.

C C are a series of circumferential hoops, shown in Figs. 3, 4, 5, 6, and 7 as attached to the longitudinal ribs B, so as to aid insustaining the boltingcloth. A

D D, Figs. 1 and 2, are spiral or'obliquely-V arranged truss-ribs extending from one end to the other of the reel and crossing each other, as shown,said truss-ribs being attached to each other at their points of intersection ,so as to form a rigid unitary truss structure adapted to give great strength to the reel, said trussribs being connected with the longitudinal ribs tween the reel-heads. The spiral ribs D D shown as passing from one side of the head Fig. 3 is a side elevation of a cylindric reel' so as to sustain the latter at points beiv IOC ` trated in Figs. 5,

A to the opposite sideof the other head in such manneras to pass half-way around.. the circumference of the reel in theirspiral course from one end to the other thereof. The degree or pitch of the spirality ofthe ribs may, however, be greater or less than shown, as may be found desirable or convenient in any particular case. The truss-ribs D D, arranged spirally,as described, may be secured at their ends to the heads in any desired or preferred manner; but, as herein shown, are secured by rivets d to lugs a upon the outer ends ot' the radial arms A of the reel-heads. shown in said Figs. l and2 is without circumferential ribs, but the latter may be employed, when desired, in4 the same manner as illus- 6, and 7. Y In FigsrB and 4 oppositely-directed spiral ribs D are shown as employed in a cylindric reel. The truss-ribs are inthis case arranged generally in the same manner as beforefdescribed; but their end portions, instead of be ing extended to and secured at the outer edges middle of the reel only, and are attached to each other at their crossing points inside of the said outer ribs, 4as clearlyshown atvd din the drawings. By this construction a great degree of stiffness in the reel is obtained, inasthe truss-ribs are to the inner faces of the heads A thereof by bolts or rivets; but the necessary connection at these points may be othto which the truss-rib trst mentioned is attached, and is also attached to other ribs which cross it in the manner shown. By this means the truss-ribs are brought to a considerable Obliquity, and a great degree of rigidity is obtained in the structure with a relatively-small The' reelV number of said truss ribs. The ribs in this construction will usually consist of metal strips,'and will be twisted at their points of intersection when necessary, so as to bring their dat faces together and there secured by bolts or rivets.

As a preferred means of attaching the trussribs D2 D2 ofthe reel-head, the radial arms A of the latter are provided with inwardly-extendingrlugs a', which are suitably located at points intermediate between the reel-axis and the outer ends of the said arms, and to which the ends of said truss-ribs are suitably bolted vor riveted, as shown.

rlhe reel-head, made with radial arms, in the particular construction thereof herein illustrated in Figs. I, 2, 5, 6, and 7, consists of a central hub, A2, upon which the radial arms Aare cast, and said arms being bent or deiiected outwardly, so that the said hub is sustained by the arms in a plane inside ot' the general plane of the reel-head. A3 is a flat ring, preferably of wood, attached to the outer ends of the arms A A and forming the reelhead proper, said ring consisting usually of a series of segments severally secured to the said arms A A and having a central opening through which the material may be fed to the reel. The outwardly curved or bent form of v the arms described and shown obviously brings the ring Aoutside of the hub A2, so thata concave open space or depression is formed within the head of the reel, which concave space or depression, communicates with the interior of spaces or openings A of the head. v

One important advantage gained by the employment of heads made in the manner described is that such heads enable the material to be operated upon to be easily conducted into the reel by bringing the exit end of a spout or conductor to a point within the ver tical plane of the head A, obvious that the material falling from a spout thus located will pass between the arms A A and will fall upon the cloth within the reel. This form of head is claimed in connection with truss-ribs of the character herein shown, for the reason that such form of head affords a convenient and advantageous means for supporting saidv truss-ribs when the latter areA bent or deflected inwardly at their ends, as above set forth. The main feature of novelty inmy invention 1s comprised in a reel-frame embracing two sets of spiral or obliquely-directed truss-ribs extendingfrom end to end of the reel,arranged to cross each other and secured together at their points of intersection to form a truss' in the manner above set forth, together with exterior longitudinal tained by said truss-ribs, and a reel-frame thus constructed is herein claimed without restricltion to any of the other features of construction herein illustrated and above described.

A construction in which two sets of obliquel yit being entirely' cloth-supporting ribs susd IOO the reel by means of the p betweeny the radial arms directed truss-ribs extending the fulllength of the reel, crossing each other and secured togethr at their points of intersection, are employ ed in connection with exterior clothsupporting ribs, and in which said truss-ribs are converged toward the center of the reel at the ends of the latter, is also new, and is herein claimed as part of my invention, as is also a reel-frame embracing the parts last above set forth, combined with a reethead constructed for the attachment of the ends of the inwardlyconverged truss-ribs, in' the manner illustrated in the accompanying drawings and above set forth.

I claim as my invention- 1. In a boltingreel, the combination, with a frame comprising exterior' longitudinal ribs for supporting. the cloth, of two sets of spiral or obliquely'directed truss-ribs arranged to cross cach other and secured together at their points ot' intersection to form a truss, said trussribs being extended the full length of the reel and connected with and constructed to support the exterior ribs, and means supporting the said longitudinal ribs and truss-ribs at the ends of the reel, substantially as de scribed.

2. In a bolting-reel, the combination, with a frame comprising suitable exterior ribs for supporting the cloth, of two sets of spiral or obliquely-arranged truss-ribs arranged to cross t of intersection to form a truss,

each other and secured together at their points said truss-ribs being extended the full length of the reel and connected with the exterior -ribs of the reel and converged toward the center of the reel at the ends of the latter, and means supportingthe said exterior ribs and the truss-ribs at the ends of the reel, substantially as described.

3. In a boltingreel, the combination, with the cloth and exterior ribs for supporting the cloth, of two sets of spiral or obliquely-directed truss-ribs arranged to cross each other and united at their intersecting points to form a truss, said truss-ribs being connected with the exterior ribs of the reel and converged toward the axis of the reel at the ends of the latter, and reel-heads comprising central hubs located inside of the planes of the heads and provided with radial arms, which are outwardly bent or deflected to form hollow or concave spaces at the ends of the reel, the inwardly-bent or converging euds of the truss-ribs being attached to the said arms near the hubs, as described.

In testimony thatI claim theforegong as my invention I affix my signature in presence of two witnesses.

substantially WILLIAM E. GOBTON.
